The sample size is the number of pixels in either dimension that correspond to a single pixel in the decoded bitmap. For example, inSampleSize == 4 returns an image that is 1/4 the width/height of the original, and 1/16 the number of pixels. Any value...

Each pixel can be set to a given color but exactly what color depends on the type of the pixel. The first two parameters give the width and the height in pixels. The third parameter specifies the type of pixel you want to use. This is where things can get complicated. The specification ARGB_8888 means create a pixel with four channels ARGB - Alpha, Red

Android How To Create A Bitmap Pixel By Pixel
6/12/2018 · If the bitmap is W pixels wide, then its stride S is W*4, and pixel X,Y is the four bytes (ARGB) starting at X*S+Y . See the WriteableBitmap.PixelBuffer documentation and samples . If you want higher level accessors then you'll need to use something like the (third party) WriteableBitmapEx you mentioned in your initial post.
- I sent a whole day trying to understand how to create a greyscale bitmap until I found this topic ! Works as is. Great !
- The Bitmap.createBitmap(int width, int height, Bitmap.Config config) method simply says to give it a height and a width. There is no indication if these are actual pixels or dp pixels.
- Create Bitmap object, as big as your visible screen. Also create a View object and implement onDraw method. Then in native code you'd load libjnigraphics.so native library, lookup functions AndroidBitmap_lockPixels and AndroidBitmap_unlockPixels .
- Enables or disables dithering of the bitmap if the bitmap does not have the same pixel configuration as the screen (for instance: a ARGB 8888 bitmap with an RGB 565 screen). android:filter Enables or disables bitmap filtering.
